One of the most talked-about plays in the Green Bay Packers' 26-21 victory over the Dallas Cowboys on Sunday was an incompletion.

Late in the fourth quarter, the Cowboys went for it on 4th-and-2. Cowboys quarterback Tony Romo threw deep to receiver Dez Bryant. It was ruled a catch and then overturned on coach Mike McCarthy's challenge.

Thus began the controversy.

The NFL on ESPN posted a "frame-by-frame look of Dez Bryant's catch/no catch."

It didn't clear up anything, except that it still looked like a catch, according to our eyes, but wasn't a catch, according to the rules. The Packers took over on downs and were able to run out the clock.

In this age of social media and Twitter, Dean Blandino, the vice president of officiating for the NFL was able to tweet within minutes why the call was overturned.

Bryant going to the ground. By rule he must hold onto it throughout entire process of contacting the ground. He didn't so it is incomplete.

New Jersey Gov. Chris Christie, who had become a good luck charm for Cowboys owner Jerry Jones, was in a suite. @SBNation tweeted two photos, a jubiliant one after last week's Cowboys wild card win over the Detroit Lions and a dejected one after Sunday's loss:

Christie's presence might not have made a lot of sense, but Wisconsin Gov. Scott Walker's did. He met with team "owners" (i.e., Packers fans) and also was introduced to Jeremy Wilcox, the bearded Wausau-area man who caught quarterback Aaron Rodgers' attention. Walker tweeted a photo of himself giving the beard a tug:

It includes a photo of five Seahwaks tackling running back Eddie Lacy when they met in the first game of the season.

The #12shashtag refers to the crowd, dubbed the 12th man.

The number 12, of course, will be well-represented on Sunday. It's the jersey number for three of the four quarterbacks playing — Rodgers, Andrew Luck of the Indianapolis Colts and Tom Brady of the New England Patriots — as well as the 12th man.

The @NFLnetwork pointed that out: "Which 12 will have the biggest impact on Championship Sunday: #Brady #Luck #Rodgers #12s?"

Sure enough, 94.5 FM, The Lake, in Milwaukee, has a "Say no to Seattle" campaign. The website says: "To help change the karma and give the Packers all the support they need for Sunday's big title game, 94.5 The Lake has chosen to 'Say No to Seattle.' No Nirvana, no Pearl Jam, no Heart, until the Packers beat the Seahawks on Sunday! Go Pack Go!"

Music videos surfaced this week for both teams. Hawktown Funk's video was linked by @downtownseattle:

The pep rally is at 4 p.m. Saturday at the Mustard Seed Grill & Pub in Bellevue, Wash. It's a home-away-from-home for Packers fans as the Northwest Packer Backers who gather at the pub to watch Green Bay games.
